For the serious caver, the limestone hills around Ingleton contain some
of the most extensive and challenging potholing in the country. This includes
the Kingsdale Master System in
Kingsdale
and
Easegill Caverns
/
Lancaster Hole
"Three Counties" system on nearby
Leck Fell
- containing many miles of subterranean caves to explore
(though much of these systems are difficult and
dangerous, and should only be attempted by experienced potholers).
